Abstract

L'invention concerne un procédé pour préparer des complexes du type hydrocarbylozyzirconium or hydrocarbyloxytitane, où le métal est à un degré d'oxydation bas. Dans ce procédé, on met en contact le complexe correspondant à dégré d'oxydation haut avec un alkyle lithium utilisé comme agent réducteur et on récupère le produit résultant.
